I wrote a User Definied Function and saved it in Module1 in Personal.xlsb
but it works only from the Immediate window and only if the "personal.xlsb"
project is selected in the project window in VBE.
All tutorials in internet say that saving the function in any module in
personal.xlsb is enough to have it available in any worksheet.
Why it doesn't work?
Please help.

TIA
David
